I am building a stock/mod bike. I'm buying a new exhaust for it. Looking for some input on a good pipe for a somewhat stock motor. I have really no price range as I can get deals on everything where I work. So far I am looking at the Leo Vince, BBR D2, Yosh Carbon, FMF 4.1, etc...



All good pipes. I can get the Leo and the D2 for next to nothing so there my top 2 choices so far.

for wut motor and wut kind of riding?

ahh completely forgot... Thanks



Its a stock 70 motor in my stock bike. Its for a backyard racer but I will take it to the track and race it. Don't want something very loud because I will ride in the backyard and I have neighbors..

 

[PitRacerVince]

well the D2 can use a silncer right? and u get those for cheap so it sounds like a good idea IDK about the leos no experience with them at all. bgut the yosh's r loud I hear.

I like the Two Bros M-6 because it deliveres a better all around power unlike the D-section and the FMF IMO.

Get the one you can get the best deal on. Stock crf 70 has 3 hp no pipe is going to get you more then 1/4-1/2hp at best.

Yea I know hahah. Pipes are worthless on a stock motor. I'm in between the D2 and the Leo.

Pull the head gasket out and take it apart useing only one of the black gaskets and you will get more power then a pipe on a stock bike.

Ti-Force Hands Down! I have 3 of these exhausts and have ran 75% of the other exhausts on the market and I have had the best results with em.



I currently have 1 on my stock/mod, my BBR Super-Pro Full Mod, and I have one in the mail I just bought for my Street Legal Supermotard CRF50.



I have nothing to say about this exhaust but good things, Best quality available, not crazy loud(actually quieter than most), FULL titanium(most other Ti exhausts on the market arnt full Ti but only Titanium piping), and there actually getting discontinued so you can get them for about 40% off as I did with my last one that I should be getting VIA UPS tomorrow.

Really? I was also looking at the old Akraprovic exhaust too. I'll check to see if I can get a TI-Force pipe.

ill second that!

ive been told that on a stock 50 the best pipe was the.....

stock pipe with the baffel removed!!! im sure it was on a video back in the days they run it on a dyno with some other pipes



fast50s speed pipe is a good performing pipe for smaller cc motors

the ti force on the other hand is more rated for the high cc motors

the header on that pipe is huge



oh and dont forget to do the head gasket mod for more compression

+1

That or fmf power core or fast50's...all those are great for a small bore motor.

All those other high end pipes are for bigger bore motors and will hinder low end torque.

I'm going with the BBR D2 or the Leo Vince.

i had a yoshi on my crf70, best sounding and performing pipe i owned. i had a tbr pipe on my ttr50 and really didnt care for it, and my nephew has a fmf on his xr50 and its pretty quite.

the fmf is a pretty quiet pipe for sure. today i put the tbr big bore pipe and played with the carb a little and its pretty sweet!

I have only used the BBR round, BBR D-section, and FMF PC 4 on stock. The Powercore 4 seemed to add a little (seemed like it anyway) and was the quietest of the 3.
